Which one of the following is the best example of action research? A) A college professor recruits sixth graders to come to his lab, where she assesses their responses and reaction times in a variety of challenging problem-solving tasks. Her results will help her refine the theory of problem solving she has been developing. B) A graduate student quietly observes adolescents' behaviors in the school cafeteria. He plans to describe his observations in his master's thesis. C) A teacher gives her students a questionnaire that asks them to describe how often they study and what kinds of strategies they use when they study. She will use the results to develop several lessons on effective study skills. D) All of the school districts in a particular state are instructed to give the same mathematics achievement test to their high school juniors. The average test scores for each district will be presented in a report that will be released to the general public.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
